DRAIN LINING

epros ® DrainLinerPP (mit PP-Beschichtung)
In trenchless rehabilitation methodology, a general distinction is made between
sectional or part repairs by means of patch or short liners and complete (full-length)
renovation of sewer and pipe runs using cured-in-place pipe lining (CIPP) techniques.
The renovation of non-man-entry sewer lines with full-length CIPP liners has
established itself as a sophisticated economical and technical alternative to
traditional repair techniques involving digging up the ground.
This method has become a proven and reasonable-cost solution for the basic
renovation of service lines in need of repair by extending their service lives for
another life cycle of at least 50 years.
A basic condition is that the materials used in CIPP operations are suitable for this
type of application and that the installation process meets stringent quality criteria.
Trelleborg Pipe Seals Duisburg provide all liners for the rehabilitation and repair of
main lines, lateral pipes, vertical pipes and diverse pipe lines with or without bends.
Various product lines geared to the particular needs are available:
epros
® DrainFlexLiner * with PP coating/installation aid

epros ® DrainPlusLiner (PUR) with PUR film/installation aid
epros ® DrainPlusLiner (TPU) with TPU film/installation aid

DRAIN LINING
• e p r o s ® DrainFlexLiner * for pipe lines and sewers having diameters from
DN 100 to DN 1200 ** .
For installations according to DIBt specifications use the nominal pipe sizes
given therein.
• Use for lines with bends up to 45° - without changes in nominal size.
• Suitable for being installed in circular, egg-shaped and special sections.
• Qualifies for steam curing thanks to its high temperature resistance.
Specifications
Material
Polyester needle-felt tube (PES tube) with a polypropylene coating (PP).
The coating (approx. 300 µm) is deemed an installation aid. The special
formulation gives the new PP liner its extraordinary elasticity (DN 225 -
DN 1200). This particular flexibility is also true for smaller diameters
(DN 100 - DN 200) due to a special PP-based coating used for this specific
purpose only. Undersize; 10%
Wall thickness
Wall thicknesses between 3 and 21 mm can be selected, depending on the
results of the design calculations.
Suitable resins
The epros ® DrainFlexLiner can be used with epoxy, silicate or polyester resin
systems.

epros ® DrainPreLiner
Ideal for protecting resins from infiltration. 9
DRAIN LINING
The preliner is a thin but resistant protective PE film tube (approx. 200 µm).
Generally, its use is not mandatory, because it provides no structural stability
to the liner. The preliner will remain in place and cannot be removed.
Under certain circumstances, however, a preliner is pulled or inverted into the
host pipe prior to liner installation in order to form a barrier between the pipe
wall and the liner to prevent the resin from direct contact with the host pipe,
or avoid damage to the liner.
Applications (examples)
• Absolutely necessary e.g. in groundwater-saturated zones
(groundwaterinfiltration).
• For rehabilitation of displaced joints where water accumulations before liner
installation cannot be avoided.
• Absolutely necessary if using the rapid ambient curing epoxy resin systems
epros ® EPROPOX FC15 or FC30.
Available sizes: DN 100 to DN 1000

Calibration Hoses
The rehabilitation of pipe runs according to the epros ® DrainLiner open-end
method always requires a calibration hose to be inverted. This is necessary to
support and expand the liner, which is loose in the line due to the open end,
and to hold it expanded until final cure.
The supporting calibration hose can be inverted along with the liner, e. g. if a
head of water (water column) is used for installation. However, if an inversion
drum is used, it is advisable to invert the calibration hose in a second step
after liner inversion only in order to use the inversion drum‘s full capacity in
terms of lining length. The subsequent installation of the calibration hose is
also required in case of dimensional changes, because simultaneous inversion
would not allow the liner to be optimally expanded to the largest host pipe
diameter.
On the other hand, if vertical pipe runs like drop pipes are to be lined, it is
important to invert the calibration hose together with the liner tube, because
the hose will stabilize the length of the liner during installation and prevent
the liner from getting too long by its sole dead weight or from being contracted
„from the bottom to the top“ during the lining operation. What is important is
to keep the liner under pressure in order to maintain a minimum stability.
